Original application filed Octoberd, 1924, Seria1ltlof740fl79, Divided andthis applicationhledJune 11,

The object of 'my invention is to provide novel, manually operated means such as a. .belt shifting lever for gradually Starting the winding, step' by step, to insure easy starting and to prevent jerks on the yarn tending to break the same, the stop for intermediateposition of the starting lever being adjustable to obtain'the best results.-

A still further object is to provide a telltale on the winding shaft for indicating the speed of the'shaft so that when the shaft reaches a predetermined speed the starting lever may be moved from its intermediate position to its next position to bring the windingmechanism up toits full speed.

A practical embodiment of my invention 7 .lS represented in the accompanying drawpower,

ings, in which- Fig. 1 represents in Side elevationso much of a winding machine as Will give a clear understanding of my improvements applied tl1,eret0.

' 2 represents the winding machine in top plan with the manually operated starting lever shown in fulllines in the position it assumes when the machine is idle; in dotted lines the intermediate position it assumes when the machine is being started, and in dot and dash lines the position it assumes when the machine is in full running position.

Fig. 3 represents a detail section, on an enlarged scale, taken in the plane of the line III-J11 of Fig. 2, illustrating the means for adjusting the position of the intermediate step in the movement of the starting lever.

Fig. 4 represents a detail front View of the tell-tale.

The winding machine frame is denoted by 1 and the winding heads on opposite sides of the machine by 2;

The drive for the winding machine includes the drive shaft 3, provided with the fast and loose pulleys 4 and 5. The driving belt 6 leads from any suitable source of not shown herein. The drive shaft 3 is connected to the winding shaft 7 through the usual intermediate belt and pulley connections. vThe winding shaft 7 is provided with a tell-tale 8 at the end' of the machine for visually indicating to the operator the rotative speed of the winding shaft.

The means which I have shown for sup- .one end of the machine.

the

block 49 in its adjusted position.

plying yarn to the winding machiiiie comprises a vertlcally arranged-supplyspool 9 which is remoi a'loly positioned upon the base support, located at 10 of a suitable bearing A manually operated means is provided for startingthe winding gradually and thus preventing the jerks on the yarn, which 'means is constructed, arranged and oper ated as follows:

A loop 42 of a belt Shifter embraces the driving belt ,6, from which loop-leads a belt shifter rod 43' lengthwise of the machine to the end adjacent the yarn supply spool; The lever for operating the belt shifter is denoted at 44, which lever is pivoted ona bracket 45 projecting from the end ofthe winding machine frame, the short arm 46 of which lever is connected to the belt shift er rod 43 and the long arm 47 of which lever extends to a position in proximity to the yarn supply spool'so that asingle operator may control the starting and-"stopping of the machine as well apply the manually operated brake for the supply spook Adjustable means are provided for causing the belt shifting or starting lever to be moved in successive steps so-that the winding operation will be started gradually and thereby eliminate undue strain on the yarn,

which means is constructed as follows:

An arm 48 projects laterally from the bracket 45, which arm is provided with an intermediate stop block 49, adjustable toward and away from the bracket 45 by an,

adjusting screw 50, bolts 51 passing through elongated slots 52, serving to clamp the stop The top of the stop block is slightly above the top of the bracket 45, so that when the starting lever is moved to start the winding operation the arm 47 of the lever will engage the stop block 49 before the driving belt 6 is fully shifted from the loose pulley 5,011. to the fast 7.

pulley 4. The operator can then watch the tell-tale 8 and when the winding operation has gradually come up to the predetermined speed, the arm 47 of the starting lcvermay" be slightly raised and its movement comthe block-49 to its pleted along the top of full running position. Thearm 48 is provided with uprising abutments 53, 54, for

limiting the movement of the starting lever. The parts of the machine shown and described, but not claimed herein, relating to the common supply spool forms the subject matter of my copending application filed October 1st, 1924, Serial No. 740,979, of which this is a division.

It is'evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my in vention; hence, I do not intend to be limited to the particular embodiment herein shown and described, but

\Vhat I claim is 1. In a manually operated belt shift-er, a support and a belt shifting lever pivoted thereon, said support being provided with stops for limiting the movement of the lever and an intermediate adjustable stop mounted on said support in position to engage the lever when the lever is moved from one limit toward the other limit of its movement, requiring deflection of the lever arm to complete its movement.

2. In a manually operated belt shifter, a bracket and a belt shifting lever pivoted thereon, said bracket being provided with a lateral arm having two uprising abutments for limiting the movement of the lever and an intermediate abutment mounted on the lateral arm in position to engage the lever when the lever is moved from one limit toward the other limit of its movement, requiring deflection of the lever arm to complete its movement.

3. In a manually operated belt shifter, a bracket and a belt shifting lever pivoted thereon, said bracket being provided with a lateral arm having two uprising abutments for limiting the movement of the lever and an intermediate adjustable abutment mounted on the lateral arm in position to engage the lever when the lever is moved from one limit toward the other limit of its movement, requiring deflection of the lever arm to complete its movement.

' 4.- In a manually operated belt shifter, a bracket and a belt shifting lever pivoted thereon, said bracketbeing provided with a lateral arm having two uprising abutments for limiting the movement of the lever and I an intermediate stop block, the top of which is slightly above the top of the bracket in position to engage the lever when the lever moved from one limit toward the other limit of its movement, requiring deflection of the lever arm to complete its movement.

5. In a manually operated belt shifter, a bracket and a belt shifting lever pivoted thereon, said bracket being provided with a lateral arm having two uprising abutments for limiting the movement of the lever and an intermediate adjustable stop block, the top of which is slightly above the top of the bracket in position to engage the lever when the lever is moved fronrone limit toward the other limit of its movement, requiring deflection of the lever arm to complete its movement.

In testimony, that I claim the foregoing as my invention, I have signed my name this 4th day of June, 1925.
